    摘要: Disclosed are compositions of DAC-B hydrocarbon resin and a poly(ethylene terephthalate) type polyester, a poly(tetramethylene terephthalate) type polyester, or a poly(1,4-cyclohexylenedimethylene terephthalate) type polyester. These compositions have a lower melt viscosity at elevated temperatures than the polyesters alone and can therefore be melt spun into fibers at a lower temperature than the polyester alone. Fibers spun from these compositions have properties substantially equivalent to the properties of fibers spun from the polyester alone.

    摘要: A bracket for use in mounting a roller door assembly to a wall comprises a plate having a bearing for support of a drum or end drum, the bearing being closer to one edge of the plate than another, and edge flanges whereby the bearing may be mounted at either of two distances from the wall. Preferably the edge flanges have interengageable formations facilitating stacking of door roller assemblies with the flanges of the brackets edge to edge.
